Measurement of f$_{1}$(1285) production in pp collisions at $\mathbf{\sqrt{{\textit s}}}$ = 13 TeV

(1285) resonance using the ALICE detector in inelastic proton--proton collisions at a center-of-mass energy of 13 TeV. The resonance is reconstructed at midrapidity (

|y| <

0.5) through the hadronic decay channel f

_{1} (1285) \rightarrow \mathrm{K^{0}_{S} K^{\pm}\pi^{\mp}}

. Key measurements include the determination of its mass, transverse-momentum integrated yield, and average transverse momentum. Additionally, the ratio of the transverse-momentum integrated yield of f

_{1}

(1285) to pion is compared with calculations from the canonical statistical hadronization model. The model calculation, assuming a zero total strangeness content for f

_{1}

(1285), reproduces the data within 1

\sigma

deviation, shedding light on the quark composition of f

_{1}

(1285).
